Opti-Gard is a high-performance reverse acting rupture disc (bursting disc) from OsecoElfab. It offers a high operating ratio of up to 95% combined with an industry-leading burst tolerance of +/-3%. This enables exceptionally high performance to support process safety and efficiency.
Opti-Gard features a smooth surface finish and can be supplied with an optional fluoropolymer liner on the process and/or vacuum side. It withstands full vacuum and high levels of back pressure without additional vacuum support to ensure the maximum free-flow area on burst.
Opti-Gard covers a wide range of sizes, burst pressures, and materials, making it an ideal multi-purpose pressure relief solution. The disc performs equally well with liquid, gas or vapor, and is suitable for a wide variety of process conditions. Opti-Gard is non-fragmenting and can be used to isolate pressure relief or safety valves.
When installed as part of our stock rationalization program, Opti-Gard can reduce stock holdings by up to 65%. This offers significant cost savings with reduced variance in inventory and installation, without affecting quality.
We supply Opti-Gard as standard with a magnet for our non-invasive burst detection system, Flo-Tel. Flo-Tel offers a practical, reusable solution for detecting when a rupture disc has functioned. The sensor is non-invasive to the process and is therefore unaffected by downstream pressure fluctuations or corrosion.
After an overpressure event, the sensor does not need replacing, which eliminates the need for expensive re-wiring costs and maintenance planning. Our dual-certified dual-certified Exd/EXia/b system Flo-Tel XD offers the same non-invasive burst detection for hazardous and explosive environments.
We also supply the Opti-Gard with a high-strength magnet for use in 22cr and 25cr duplex holders. Our specially developed high-strength magnet means you can still use our unique, non-invasive burst detection systems Flo-Tel and Flo-Tel XD for accurate signaling up to 140°C. Standard rupture discs will not allow this, as the duplex stainless steel is magnetic and prevents the detector from functioning correctly.
